Dynamon EW is a polymeric slump-retaining admixture designed to stabilize the concrete consistency for two hours or more, with little or no effect on set time at the recommended dosage. Dynamon EW is engineered using time-release polymer-based components in order to maximize slump-retention with minimal impact on set time. Because the time-release dynamic is strongly influenced by the job-specific cement chemistry, there are three distinct products available. The appropriate selection (10, 11, or 12) may be verified in conjunction with MAPEI Technical Services. Dynamon EW conforms to ASTM C 494 Type S and CSA A23.1.
